上海正堂是**生產(chǎn)HB大功率齒輪減速機的廠家，是集研發(fā)，生產(chǎn)，銷售于一體的減速機集團；
HB斜齒/傘齒系列大功率減速機是全新型硬齒面減速機，具有大轉(zhuǎn)矩范圍，采用單元結(jié)構(gòu)模塊化設(shè)計可臥式安裝也可立式安裝。有實心軸、空心軸和收縮盤空心軸輸出。應(yīng)用范圍廣。
采用高強度**合金鋼滲碳游淬火，具有高**壽命齒輪及高許用軸向，徑向載荷，運行噪音低，**性高，結(jié)構(gòu)緊湊等優(yōu)點。
H系列經(jīng)過正堂減速機改造有如下**：
1.零部件種類減少而規(guī)格數(shù)量增多
2.傳動功率增大，運轉(zhuǎn)**性提高
3.可以采用性能優(yōu)異的非接觸式和**的迷宮式密封裝置
4.可以提供適于狹小空間安裝的法蘭軸
5.采用mssak計算機程序設(shè)計吸收噪音的箱體結(jié)構(gòu)
6.實現(xiàn)特大的齒面接觸比
7.增大了風(fēng)扇和新型的導(dǎo)流系統(tǒng)
8.增大了箱體的表面積
9.采用圓錐齒輪削磨工藝
10.模塊化單元結(jié)構(gòu)
具體如下型號：
